ABB Surge arrester OVR SL30L/I

The plug-in surge protection terminal blocks OVR SL provide combined protection, tested in categories D, C, and B (according to IEC/EN 61643), for twisted pair cables used for signal transmission that require either lower contact resistance, higher current, and/or a wider frequency range. They are suitable for direct current applications up to 750 mA and an operating voltage of 6 to 110 volts. Designed for use at the boundaries of LPZ 0 to protect against surges up to LPZ 3, safeguarding sensitive electronic equipment.
